摘要
根据恶臭气体在一定波长范围内的强吸收光谱特性,该文采用紫外差分吸收光谱法,设计了一种恶臭气体监测仪器。利用球面反射镜近轴成像原理,将光源发出的光进行准直后,经角锥阵列反射,由光谱仪对信号进行处理与转换,自动快速地检测恶臭气体的实时浓度,并实现数据的传输和打印。
The effluvium is strong to absorb spectrum within the scope of certain wave-length. The paper designs an instrument for effluvium monitoring with UV differential optical absorption spectroscopy. After collimation and reflection of pyramid array for the light from light source based on spherical mirror adaxial image theory,the spectrograph processes and converts the signal. The monitor can automatically and rapidly examine the real-time concentration,then delivers and print the data.
